The system checks the tire pressure and the tire
temperature of the tires fitted to the vehicle by
means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in the first time they are
driven.
The tire pressure and the tire temperature
appear in the multifunction display
(
→
page 219).
If there is a substantial pressure loss or if the
tire temperature is excessive, a warning will be
given:
R
Via display messages (
→
page 438).
R
Via the h warning lamp in the instrument
cluster (

page 469).
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pressure
suitable for the operating situation. Set the tire
pressure for cold tires using a tire pressure
gauge. Note that the correct tire pressure for the
current operating situation must first be taught-
in to the tire pressure monitoring system.
In most cases, the tire pressure monitoring sys‐
tem will automatically update the new reference
values after you have changed the tire pressure.
You can, however, also update the reference val‐
ues by restarting the tire pressure monitoring
system manually (

System limitations
The system may be impaired or may not function
in the following situations:
R
If the tire pressure is set incorrectly.
R
If there is a sudden pressure loss caused, for
example, by a foreign object penetrating the
tire.
R
If there is a malfunction caused by another
radio signal source.
